To whom it mayroncm:

Be it known that' I, FnAnK DRAYTON BELKNAI", a citizen of the United States of I America, and a resident of th'e borough of Improvements in -Manhat-tan, city',county,and State of New York, have invented certain" new and useful Card-Type-WVriting Machines, of which the followingiis a specification."

Mly invention relates to typewriting machines in general and more particularly consists of improqed apparatus. for facilitating the writing' with, regularity .upo'n predetermined portions of; cards prsmall strips of paper.

In certain types-of add I I --it becomes necessary to yvrite in perforated of parchment,

letters 1 upon 'a card or strip or to write on" cards formedof waxed' paper,

i located at the'saine' place on each card and and,- in. order that suchf c ards or ,str ps of parchment shall perform their proper function inthe addressingmachine', li lS im portantthat the writing'fshall always be thatthe cards shall be fed-to the machine in a flat or nearly flat condition andshall,

' be delivered after stenciling orprinting by 4 ment. I for the standard typewritingfmachine WlllCh the machine in thesame condition. It is difficult, if. not impossible, with the ordi-' nary typewrltingmaehine feeding dev ceto secure thisaccuracy, and the apparatus designed to" hold the paperinj-position on an vordinary typesrritinrg. machine does nothing] itself readily to thelpr'oper'holding" of such cards or smalll'strips of paper or parch- I- have invented certain attachments overcome these difficulties and perfected thesame after'long experimental use." 1

Apparatus embodying the preferredfprm V of the invention at' present known to -me' is;

illustrated in. the accompanying sheet, of

"drawing in which,

-Figure l is a plan view-'ofjthe platen platen supporting. carriage with "attachnientsx, Fig. 2 is a detail crosssection on i line 2'2 of Fig. -I,'showing a card iinrposi tion for writing the'first linevof lthe' iit dress on it.- Fig. 3' is a similar View showing. the

card in position for writing the last line on it, and Fig. 4 is a detail View showing the clamp in open position ready to receivethe card.

Throughout the drawings like reference figures indicate likepa-rts. 1- represents the ordinary carriage of a typewriting machine, and 2 is the platen for ress ing machin s atxits outer end, as 'by ri'yets orf sci w to said platem' Theflotl'ier leg 9, oil

The mode of operation V as follows: Normally, the pl' 'ten isin the of the platen. .leg 9 prevents its inper end from being bent.

- feeding and supporting .;.the fp ap er which may preferably be providedfwith a pad 2 for -'use'in combination-w'th the perforating type if such type is employed..- This platen is monnted on a shaft 3,'- journaled in ca riage 1,. and said shaft may be turned by meansof the buttons 4, 4, on its ends.

5, 5, are bars extending across the/"carriage from which are supported strips of metal "6, -6, sometimes. slightly curved as shown, which serve asguides to throw the card holding-clamps into operation. The card holding clamp consists. of a -V- sha' ed or piece of'inetal, one leg of;,w-hich* (1 against the. platen, beings fastened r 2 5 7 H the :V-

shaped spring, normally extends otitivard,

gas-shown in Fig. 4:, so-- as'to leavefan open space in which the cardlO, or strip of paper may be inserted. reinforced. or made of extrathickness-so ve it greater s't-ifiness'than thecurved This leg 9 is pre Eel-ably 13 isaregister in the shape strip arranged circumferentially of one end. ofthe n and marked 'With suitable chinsions or numbers 1, 2,3,- as shown in Fig-l. This reo-ister cooperates with the pointer 14," which, as 'shown, false acts to cover up. such portion of the register-as in'ay hebelowit.

19 is a stop or projection on-the carriage 1 and 20 and 21-areprojecting-pins on the end. of the platen 2, which coiiperate'swith the stop -19, to "limit themovement of theplaten-in either direction,

of my iiiy e'ntion is position'sh'oivn n Fig.4, which means that the em 21 is. in contactwitli theprojection 19, an the ca-rd'to be perforated "or other- 4, 4, the card will. be drawn down'in front {of and under the plate-Inland the spring clamp-caused to grasp thesnme by'the action ofsthe guide 6,"W.hich forces the leg 9 0f the clamp to travel in approximately a straight line tangbntfio the circumference of platen while the flexible leg? partly unwinds ,andextends' its unwound portion in a similar tangent to the circumference The greater stilfhess of the wise written upon 1s -inserted by being dropped into the open clamp or clamps, as indicated-in Fig. l ingb'roken 'lihes. On fturningthe platen by meansot the buttons be .straightened corresponding proximately straight tangential location of 2 i 960,252 I v upward by'the action of the curved leg 7, and compels said curved leg to stralghten out as shown in Figs. 2 and 3. This keeps .thecard -10 flat-throughout the operatlon while holding it firmly in position for printing. When the figure 1 or the first d1.- vision of the register, appears at the end of the pointer 14, the name of the person be ng addressed may be written upon the first line of the card. Further rotation of the platen so as to expose the figure 2 of the registe'r to view, will indicate that the card IS in position for the second line, such as the street address to be written. The next partial rotation sufficient to disclose the figure 3 as shown in Fig. 1 of the drawings, will bring the card to the last position shown in Fig. 3, after which the last line or city address may be written. This means that the stop 20 has come down upon the. top of the-projection l9, and further rotation of the platen is impossible. By reversing the rotation of the platen, it is brought back into the position shown in Fig. 4L, and the card may be picked out.

The guide 6 is made slightly arc-shaped andhas a radius of curvature which is much greater than theradius-of curvature of the platen 2. This sli ht curvature and dropped portionat the bac of the machine is made necessary'by the height of the bars 5, 5. If

these bars were lowered, the guidefiicould y. 1S apides 6,-6, permits the clamps to open when tie platen is in the positionshown m Fig.

4. -I urther'more, this shaping of the guide permits the clam holding the card to run 3. This saves the .car

' outalong-the efwithout much curvature.

as shown in ,from being bentwhile in the machine. As

' these cards are filed in magazines, it is important that-they-should notbe bent. .As

they are in some cases to be used in addressing machines having straight guide passageways adapted to-operate upon flat cards,

it is also particularly important for this reason that the cards are not -'bent by" the typewriting machine.

It; is evident, of. course, that various changes could be made in the details of construction illustrated gand described without departing'fromtlie spirit and scope of my I claim:
